Two parallel lossless transmission lines have identical impedances of j per unit. The lines are connected to a common bus at the receiving end and to another common bus at the sending end. If the voltage at the sending end is 1230° pu and the voltage at the receiving end is 120°pu. If a tap changing transformer of ratio 1:1.05 is placed between the sending end of line 1 and the sending bus. If the voltage at the sending end is still 1230°pu and the voltage at the receiving end is still 120°pu, find the real power in pu transmitted to the load by each line.
Short Transmission Line
A short transmission line is a transmission line that has a length less than 80 kilometers, an operating voltage level of less than 20 kV, and zero capacitance effect.
Power Flow Analysis
Power flow analysis is a topic in power engineering. It is the flow of electric power in a system. The power flow analysis is preliminary used for the various components of Alternating Current (AC) power, such as the voltage, current, real power, reactive power, and voltage angles under given load conditions and is often known as a load flow study or load flow analysis.
Complex Form
A power system is defined as the connection or network of the various components that convert the non-electrical energy into the electric form and supply the electric form of energy from the source to the load. The power system is an important parameter in power engineering and the electrical engineering profession. The powers in the power system are primarily categorized into two types- active power and reactive power.
